Hmmm… over here, mine is green. Or at least the trash shown in it is. And I’ve just updated Deepin an hour ago, so I’m certainly using the newest packages. When did you start experiencing this problem?

Sorry about that then . For some reason, I was thinking that you were using Deepin! If it’s KDE Plasma, then I’m afraid I may not be of as much help. However, I will certainly be keeping tabs on this thread in case something does turn up that I can add to, clarify, or help with .

Had the same problem for multiple times. Even if Trash is empty, icon is red sometimes. However, 90% of time it can be solved by rebooting. If that doesn’t work, I just run Bleachbit and set it to cleanup all the KDE stuff - does the trick every time.

just put some black tape over it
does it do the same if you change the icons ? you can also delete everything in .cache folder (loggoff required if you do) does find $HOME ! -user $USER -type f return anything bad with permissions ?

@trytip your command returned nothing about permissions.
I solved the bug after remove the trash icon and add it again by dragging it from dolphin to my desktop.
However the bug reappeared after I empty the trash using the option available in the context menu of the icon on desktop.
